Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a hook deterrent for a sewing machine with an automatic hook that attaches a hook to a front fitting portion of clothes such as pants and a skirt.

<Prior art> Conventional snap hooks or hook hooks are attached to the same side of clothing at the same time by a sewing machine with an automatic hook at the same time, but in order to attach them as a set, hold them with different combinations of hooks determined according to their respective purposes. One deterrent
A screw is attached to the tip (lower end) of the restraining rod, which is vertically movable near the needle of the automatic sewing machine, so that each hook can be restrained at once by the single restraint on the attachment surface of the clothes. Alternatively, as shown in Japanese Utility Model Publication No. 62-50572, the hook restraint is separated into two, and each restraint is attached to an independent restraint rod of the sewing machine so that each of them can be lifted and lowered individually. There was also.

<Problems to be solved by the invention> However, in the above-mentioned conventional example, first, in the former, since the holding surface of the hook restraining tool always moves vertically with respect to the mounting surface of the clothing, the mounting surface of the clothing is thick. When there is a step due to the difference, that is, the part where the hooks are attached is near the edge of the clothing, and the rabbit corner fabric is folded and compounded,
Inevitably, the thickness of the hook is not one, and as a result, the hook that touches the thick part will be held closely to the mounting surface of the clothing, but the hook that touches the thin part will not be sufficiently suppressed. .

Therefore, when the hook is automatically sewn in such a state, the hook disengages from the restraint tool and the needle and needle hole are misaligned to cause needle breakage, or the material is not sufficiently suppressed so that the material is not sufficiently suppressed. However, there was a defect that the mounting direction was twisted when viewed after mounting due to movement or distortion, and normal correspondence with each of the opposing hooks mounted on the other side could not be obtained.

Also, in the latter, since the restraint device moves up and down independently, each hook will be held on the fabric without tilting, but since the restraint devices are separated, due to vibrations during mating,
The relative position of the hooks is deviated so that the hooks cannot be accurately attached to each other.

Therefore, the present invention is intended to provide a hook deterrent that solves the above-mentioned drawbacks of the prior art.

<Means for solving the problem> Hook restrainers that are freely attached to and detached from the two cloth restraining rods of the sewing machine with automatic hooks are mutually held so as to allow mutual sliding only in the vertical direction. , And a hook deterrent device which is designed to be linked to each other with an invariable distance maintained therebetween.

<Operation> The two restraints are attached to the tips of both restraining rods by allowing them to slide only in the vertical direction at a position different from the mounting position on the restraining rods and linking them so as to regulate each other. The distance between the hook deterrents is kept constant, and each of the two deterrents independently adjusts and suppresses the step of the mounting fabric surface.

<Embodiment> Hereinafter, the present invention will be described in detail with reference to an embodiment shown in the drawings. The present invention comprises two independent hook restraints A and B. The hook restrainer A includes a hook at a front end of a support 1 and a hook. A hook holding portion 2 including a holding hole 3 into which the hook is inserted and a movable holding piece that holds down a hook (not shown) inserted into the holding hole 3 is provided. A holding hole 9 into which a hook is fitted and a holding hole 9 in the front part of the body 7.
Movable pressing piece 10 for suppressing a hook (not shown) inserted in
A hook holding portion 8 composed of and is pivotally supported horizontally by a shaft 10 'so as to freely swing.

Then, L-shaped bent mounting pieces 6 and 13 are respectively installed upright at the center of the upper surfaces of the hook restraining tools A and B, and the hook restraining tools A and B are automatically hooked by the mounting pieces 6 and 13, respectively. It is removably attached to the lower end of a restraining rod (not shown) that is vertically movable near the sewing needle of the sewing machine, and at the rear of the supporting body 1 of the restraining tool A, another supporting body 7 adjacent to the supporting body 1 is provided. An arm 5 extending toward the upper end of the arm 5 is projectingly provided, and a circular fitting piece 12 fitted into a circular notch 11 formed in the rear portion of the support 7 is fixedly provided at the tip of the arm 5 to fix both hook restraining tools A and B. Are mutually movable in the vertical direction, and the distance between the two restraints A and B can be kept constant.

Next, a series of operations of the hook restraining tool having the above-mentioned structure will be described. The respective hook restraining tools A and B are attached to the lower end of the restraining rod of the sewing machine with automatic hooks by screws respectively by L-shaped attaching pieces 6 and 13. Predetermined hooks (male or female of hook hook or snap hook) are fitted and held in the holding holes 3 and 9 of the holding portions 2 and 8 of the hook restraining tools A and B together with the restraining rods, that is, clothes or pants. Alternatively, attach the hook at a predetermined position on the skirt.

In this case, when the thickness of the mounting surface is different between the restraining tools A and B, the restraining tools A and B are adapted to the respective thicknesses by slipping between the circular notch 11 and the circular fitting piece 12. Absorb the step,
Hold each hook down on the mounting surface.

Further, a step is formed in the left and right thicknesses, for example, when the restraint tool B rises to the right, the tilt angle is θ ₁ , and when it rises to the left, the tilt angle is θ _2, and the hooks of the restraint tool B are always averaged with respect to the mounting surface. It acts to suppress and stabilize.

As described above, both deterrent tools A and B independently exert a depressing action on the fabric surface, but not only the distance between the deterrents is maintained only by the deterrent rod, but also the space is more reliably and stably maintained by the arm 5. There is.

<Effects of the Invention> Since the present invention is configured so that the two restraining devices operate independently as described above, even if there is a step on the hook mounting surface of the clothing, the thickness of the mounting surface can be reduced. The hook retained on the restraint corresponding to the thin part is floating with respect to the mounting surface,
In other words, it is possible to freely cope with steps on the mounting surface without being in a state where it cannot be sufficiently suppressed.

As a result, since the hook does not sway, the number of needle breaks due to the misalignment of the needle hole is greatly reduced.

In addition, since the number of needle breakages is small, the chances of misaligning the various parts of the mechanism caused by the impact at that time are significantly reduced.
Since the cloth of the hook mounting portion is sufficiently suppressed and held, the cloth does not move laterally or twist, so that the mounting position and direction are accurate.

Furthermore, two kinds of restraints are equipped so that two types of hooks, male and female, can be attached at the same time. Both restraints can freely move in the restraining direction, but in the front, back, left and right directions. Since they are regulated with each other, the space between the hook holding portions is kept unchanged, and it is a highly practical idea having many excellent effects such as not disturbing the correspondence with the mating hook.
